  1. Visit by Government Officials from Mozambique COLUMBIA RIVER SYSTEM BRIEFING II U.S. Army Corps of Engineers Northwestern Division North Pacific Water Management Portland, Oregon 15-16 October 2001

  2. WATER MANAGEMENT DIVISION RESERVOIR CONTROL CENTER HYDROLOGIC ENGINEERING BRANCH POWER BRANCH • Flood Control Plan & • Oversight • Forecasts Review • Hydrologic Model • Development • Water Control Data • Water Control Manual • Approval Implementation of Annual Operating Plan Real Time Operation Develop and Implement Fishery Plan • Annual Operating Plans • and Oversight (PNCA & • Columbia River Treaty) • System Operation • Studies • Hydropower System • Analysis Center • of Expertise

  3. Operational Planning Unit Hydropower Analysis Center of Expertise (to be covered later) POWER BRANCH • Treaty Storage Regulation Studies • Assured Hydro Operating Plan • Refill Studies • Special Power Studies for Fish Operations • Annual Data Submittal to Power Pool • Coastal Engineering Coordination • HYSSR Power Model Support

  4. RESERVOIR CONTROL CENTER RESERVOIR REGULATION UNIT WATER QUALITY TEAM HYDROPOWER COORDINATION FISH TEAM

  5. WATER CONTROL DATA SYSTEM STUDIES/FORECASTING & RCC SUPPORT IM SUPPORT STAFF HYDROLOGIC ENGINEERING BRANCH

  6. CONFLICTING RESERVOIR OPERATIONS POWER: Releases matching Demand. Reservoirs full in Sep, begin draft in fall to meet Demands (which increase with cold weather); Empty by Mar; Refill with spring runoff ANADROMOUS FISH: Normal runoff pattern. Flows augmented Spring/Summer to reduce Travel Time and Summer Temperatures. Need Reservoirs Full in Apr (after Flood Control); Draft as Migration Begins; Refill during fall/winter to Full by April. Opposite power requirements. RESIDENT FISH & WILDLIFE: Stable reservoirs (Nutrient Supply, Spawning Areas Protection, & Max. Habitat). Need Stable Reservoirs (only a few feet Changes from Full); Let flood Control dictate winter/early spring Pool Elevations. More compatible with power.

  7. Regional Players -- Operations BLM NMFS (CHAIR) BIA USFWS USFS CORPS FEDERAL EXECUTIVES USBR NPPC BPA STATES TRIBES Independent Scientific Advisory Board EPA IMPLEMENTATION TEAM (IT) SYSTEM CONFIGURATION TEAM (SCT) WATER QUALITY TEAM (WQT) TECHNICAL MANAGEMENT TEAM (TMT)

  8. WATER MANAGEMENT TRENDS • Changes in Traditional Operating Priorities: Flood Control, Firm Power, Fish. • Eroding Firm Energy Generation (aMW): • ‘84 Water Budget & Spill (350); ‘92 Strategy for Salmon (50); ‘94 F&W Program (525); ‘95 Biological Opinion (325); ‘98 Biological Opinion (317). Total: 1,567 (13% of System’ Firm of 2,000; 1.5 times Seattle Use). • NEW FISH REQUIREMENTS • Flow Augmentation: more volume and for longer • Spill for-fish-passage: higher % and longer • More Players (more dynamic tension)

  9. CHALLENGES • Problems are complex • Solutions Uncertain • Consensus Elusive • Increasing Number of Players • Direct Challenge to Existing Authorities • More Fish listings • Tighter Controls on Operations • Less Flexibility to meet All Purposes • Constant Changes in Operational Priorities
